DEVICE FOR USE ON RANDING, HEEEIi-SHAVING, AND TRIIVEIYIING MACHINES.

Application filed May 12, 1921, Serial No. 468.962. Renewed January 8, 1924.

To all 107mm m (13 concern:

Be it known that Josnrrr h l. BARTON, a citizen of the United States. residing at Danvers, in the county of Essex and Commonwealth of Massachusetts, has invented certain new and useful improvements in Devices for Use on Banding. Heel.Shaving, and Trimming "Machines. of which the following is such a. *l. clear. and exact description as will en le others versed in the art to which it appertains to make and use the same.

My invention relates to devices for use on randing and heel shaving and trimming machines a-.d more particularly for use on machines designed for shaving rubber or leather heels after they have been attached to the shoe upon which they are to be worn.

llfly invention has for its objects 1. To eliminate the usual and ordinary dificulties experienced by shoemakers in shaving rubber or leather heels such as are generally used on shoes.

2. To eliminate the use of oils and other lubricants in the shaving of rubber or leather heels, thus obviating the resulting necessity of removing the same from the rubber or leather after the heels have been so shaved.

3. To provide an improved revolving mechanical, adjustable means of guarding the heels so as to insure an absolutely true contour on their finished edge.

4i. To provide a mechanical means of guiding the shaving of heels which will eliminate much of the time heretofore required, increase the output of the operator, and insure a resulting saving to the manufacturer.

5. To eliminate much of the human element in the machine shaving of'heels and avoid much of the dangers and injuries heretofore experienced by heel operators.

6. To provide an improved means of regulating and adjusting my device.

And to provide other advantages and re sults some of which are hereinafter referred to.

l accomplish the objects of my invention as illustrated in the accompanying drawings, in which Fig. 1, shows the operating portion of a heel shaving machine upon which my improved guard device is used. Fig. 2, is the view of my improved guard device which faces the cutting knivesof the machine upon which it is used. Fig.

3, is a side view of my improved device. Fig. 4, is a top view of the same. Fig. 5, shows the detail of my improved mechanical revolving guard.

Refcrrin again to Fig.

l. 1 shows the fixed portion of my improved guard device. 16., shows the adjustable. revolving, mechanical portion of my improved guard. 2. shows the cutting knife siaft of the heel shaving machine. the cutting knife being shown in dotted lines.

Referring again to Fig. 2, 3 designates the holding screws mounted in. a supportingring and which fit into the recessed runway 15, on the revolving unit 16. so as to hold said revolving unit securely in its operating position, said supporting-ring being mounted upon and is carried by an ad.- justing jack 4 by means of which my improved guard and its supporting ringds distanced from the cutting knives 2, (Fig. 1) at the will of the operator by operation of the regulating screw 5;, shoulderedat 6 and 6', and functioning by means of the threads 7. in the fixed nut 8. Said supporting-ring, and revolving unit or top-lift guard, are adapted to be supported around the cutter-shaft, and the openings through both of these members are greater in diametcr than the cutter-shaft to permit lateral adjustment across the axis of the cutter.

Referring again to Fig. 3.- 9, shows the tension screw by means of which my improved guard is firmly held at any fixed position after the required adjustment has been made by. operation of the regulating screw, 5.

Referring again to 4. 10. shows the dovetailed unit.- of my adjusting jack which. operates in a similarly shaped slide-way contained in the body portion of mydevice. Said dovetailed unit is compactly positioned within the slide-way in which it operates by means of the sliding key 12, for the purpose of eliminating the lateral play. 13, designates the holding: arm by means of which my improved device is secured to the heel shaving machine upon which it is intended to be used. 14, designates a slot in the holding-arm 13 through which the, se-

curing nuts or bolts may be conveniently passed in making my device secure.

Referring again to Fig. 5, 15, shows the recessed run-way formed on a reduced extension of the top-lift-guard and which is engaged by the holding screws 3, shown in 1 Fig. 2, said holding screws being exposed upon the outside of the supporting-ring. 16, shoWs the revolving face portionof my 1111- in operation.

proved guard against which rests the top lift of the heel during the shaving process.

The revolving face portion 16, is shouldered at 17, so as-to prevent any shppmg of the heel during the process of shaving.

To those familiar with the art. to which my invention appertains it will .be under stood that heel shaving has. heretofore been done on machines provided with revolving knives a ainst which the operator holds the heel he desires to trim while the knives. are Fixed guards have hereto fore been resorted to, but to make them usable it was found necessary to smear oil or grease upon'the heel betore the shaving process and toin turn remove such oils or grease after the shaving .Was completed. The use of oil or grease caused the heel to slip easily over the ii .d guard Whereas my mechanical revolving guard moves easily;

and steadily in the di'retion desired Without possibility of slipping or danger to the "operator. ;My improved shoulder 1'7, acts as 7 a double insurance again'stfslipping of the 'shafhfanfendless top-lift-guard having a.

end

heel or injury to the operator. 7

Hav1ng thus described my invention E claim as new and desire to secure by Letters Patentoii the United States of. America 1. In a'machine of the class'described, a

cutter-shaft; a cutter carried thereby, a topllft guard-supportad ustably mounted ad'- j jacent said cutter-shaft and provided atone with a' supporting-ring positioned around said cutter-shaft, an endless ft'opliftguard having a peripheral recessed run Way mounted in said supporting ring. the

openings through said top-lift-guard, and supportlng-ring being of greater diameter than the said cutter-shaft to permita lateral adjustment across the axis of thecutter, and means mounted in and projectingthrough said ring and engaging in said recessed runway to retain the top-litt-guurd incngagement with the ring and permit its rotation therein. i I

2. In a machine of the class described, a

cutter-shaft, a cutter carried thereby; a dove-.1

tail support mounted to be adjusted parallel w th said cutter-shaft. a top-lifeguard support 7 a djustably mounted on said dovetail support and provided at oneend' vithasup porting-ring positioned "aroz'rud cutter permit its rotation relative thereto.
